ahh I see. I keep mine flat which is where the confusion is coming from from most of us I believe. If it works for you it works! I totally understand freezing larger quantities together, when I was EPing I figured I'd be doing so for awhile and froze at least 4oz in one bag (typically 6-7oz) since I'd need several bottles worth thawed at once down the road. But then he started BFing and now I only need 2-3oz thawed at a time ugh.

I would def. try to start providing half fresh milk at least. Frozen is still awesome, but fresh milk does contain nutrients lost in the freezing process.
